I believe the correct answer is A. This is because it's asking for the absolute answer of 4, and 4=4. I hope this helps!

Consider the following sine regression model y =18.614 sin(0.521x - 1.984) + 76.900. Predict y(14). I know the answer. Will mark

rosijanka [135]

Answer:

61.512

Step-by-step explanation:

Put 14 where x is and do the arithmetic. Arguments for trig functions are always radians unless otherwise specified.

y =18.614 sin(0.521x - 1.984) + 76.900

y =18.614 sin(0.521·14 - 1.984) + 76.900 = 18.614sin(5.31) +76.900

y ≈ 18.614·(-0.82668) +76.900 = -15.388 +76.900

y ≈ 61.512

The regression model predicts y(14) = 61.512.

A metal plate, with constant density 5 g/cm^2, has a shape bounded by the curbe y = x^2 and the x-axis, with 0<= x <= 3 an

nignag [31]

Answer:

a) 45 g

b) greater (make the graph youself on desmos or something)

c) 9/4

Step-by-step explanation:

area = integral 0 to 3 of x^2 dx = [1/3x^3] 0 to 3 = 9

mass = density * area = 5 * 9 = 45 grams

area = y*deltax = x^2*deltax

x = integral 0 to 3 of 5x^3 dx / mass = (405/4) / 45 = 9/4
